1. Draw the object as a point or simple shape. 2. Draw arrows (vectors) to represent each force, with the tail on the object. 3. Label each force.

Analyze the whole system or individual masses by applying Newton's Second Law to each mass and considering the tension in the string.

The study of forces and their effect on motion.

The force pulling an object down due to gravity; calculated as $W = mg$.

The force exerted by a surface on an object, perpendicular to the surface.

The pulling force exerted by a string or rope.

A force that opposes motion between surfaces.

The collection of objects being studied.

The region around a massive object where other massive objects experience gravitational force.

The tendency of an object to resist changes in its state of motion.

The vector sum of all forces acting on an object.

The study of forces and their effect on motion, explaining why objects move as they do.

The force pulling an object down due to gravity, calculated as $W = mg$, where g is the acceleration due to gravity.

The force exerted by a surface on an object, always perpendicular to the surface.

The pulling force exerted by a string, rope, cable, or similar object on another object.

A force that opposes motion between surfaces in contact.

A defined collection of objects being studied, crucial for determining internal and external forces.

The region around a massive object where other massive objects experience a gravitational force.

The tendency of an object to resist changes in its state of motion.
